Hi All, We at Jumper are building Virtual devices to streamline automated testing, continuous integration, and delivery for embedded software development (you are also welcome to read our blog that talks about these topics). We have a live alpha th...

We a team from PSG College of Technology, Coimbatore, India created this "https://www.youtube.com/channel/UCEGFAjSXeZBtn21oagQU3yA" channel to share what we explore with NORDIC THINGY nRF52 Series kit..!!

Hello, We are currently looking for an Embedded / nRF Developer in Stuttgart that will help us to further develop FruityMesh (https://github.com/mwaylabs/fruitymesh) and our commercial Product BlueRange (https://bluerange.io/). C++ knowledge is man...

The purpose of this tutorial is to expound my notes on the studies I have done on the use of nRF51, but also serve for the nRF52, and thus share with the beginner as I of the Portuguese language. This tutorial is continuity in the [previous tutorial]...

This tutorial aims to help Portuguese language beginners, like me, with the nRF5x family and who chose to use Eclipse as a development tool. The tutorial will be very simple and we will use the Eclipse Oxygen and the GNU MCU Plugin, in addition to G...

Hi, Using Git and choosing the right workflow is essential when you want to implement DevOps practices as part of your SW development. When it comes to embedded SW things start to get a bit rough. Take a look at the blog post below to learn how to u...

Weather station created from two Nordics eval-boards (Thingy:52 and nRF52840-Preview-DK). Source code and hardware files are available. http://evalspace.com/weather-station/

If automated testing, continuous integration, and delivery processes are top of mind for you, but you are not sure how to start implementing it for embedded SW development - take a look at the following cookbook. https://medium.com/jumperiot/how-to-...

Segger RTT (Real-Time Terminal) supports multiple data channels. RTT Viewer uses channel 0 only, and implements multiple virtual terminals on top of this. The terminal can be switched by SEGGER_RTT_SetTerminal(). Channel 0 is used by NRF_LOG. NRF_LO...

Introduction The recently released nRF5 SDK for Bluetooth Mesh does not provide Keil project files for its example projects. Fortunately, it's relatively easy to set up your own project from scratch. This guide will show you how. While the list of ...

Here are two simple functions to use when you want to use timestamps for time measurement. uint32_t millis(void) { return(app_timer_cnt_get() / 32.768); } and for comperison of current with given timestamp with rollover correction (thanks to...

There are times that we needed to flash the nRF5x series on a PC where the development software were not installed. The problem could be worst when network access is limited. With a HEX file on hand, it is now possible to flash the nRF5x device usi...

Debugging interrupts in not an easy task. During the development of Jumper's Emulator, we gather few useful tips that we think can help you all when debugging the nRF52 interrupts. Hope it will help you all. https://medium.com/jumperiot/how-to-debug...

In my 2nd blog post in the series on Bluetooth 5, I go over one of the main features of Bluetooth 5: 2x speed. The advertised 2x speed of Bluetooth 5 is great! BUT, what does that even mean? Is it 2x "1 Mbps" = 2 Mbps? Is that even ach...

Embedded devices are no longer ship and forget products. Once deployed, a connected embedded device is updated and provide with services and not just functionality. This paradigm shift requires adopting DevOps practices and requires monitoring device...
